Is it possible to receive light only in the cladding?

Dear all, Is it possible to detect only the light emitted from the cladding and further more to detect the intensity from the core and cladding separately ? Thank you very much!

Some patents have mentioned the offset arrangement of two fibers which means the two are not collimated but there are a transverse displacement between the two central axis,like US.patents No.7231114 and 7120324. Is this scheme workable and are there any further materials about the operation of offset arrangement?
